Coal mine explosion in Ukraine

A blast at one coal mine in eastern Ukraine and an elevator collapse at
another killed at least 19 people. Rescuers were still searching for a total
20 miners missing at both mines. The pre-dawn blast at the notoriously
dangerous Suhodilska-Eastern mine in the Luhansk region killed 17 workers
and left nine missing. Investigators suspect the accident was caused by a
powerful explosion of methane.
